Description :
Replace the air in the 100 cubic meter liquefied gas residual storage tank with water in the gas tank, and then replace the water in the storage tank with inert gas. That is, using water as an intermediate medium for displacement. The operation process is described as follows:
1. Inject water into the storage tank from the sewage outlet, and when the water overflows from the vent, the air has been completely drained.
2. Stop injecting water, then inject nitrogen into the storage tank from the vent, open the tank drain, and the water in the storage tank flows out from the drain under the pressure and weight of nitrogen. The Shijiazhuang 50 cubic meter buried liquefied petroleum gas storage tank, 50 cubic meter liquefied gas residue storage tank, and gas tank will continue until the water in the storage tank is completely drained.
3. Close the drain valve, continue to fill the tank with nitrogen until the pressure inside the tank reaches 0.2 MPa, and always maintain a positive pressure nitrogen seal inside the tank to prevent air from entering again. This method is easy to operate, safe and reliable, and has a short cycle.Note: When replacing with water, it is strictly prohibited for the hydrocarbon pump to enter the water.

(II)Open tank maintenance of liquefied gas storage tanks
1. Nitrogen replacement
1.1. Open the tank vent valve and vent the liquefied gas remaining in the tank. When the pressure drops to around 5000Pa, close the vent valve. Maintain the pressure inside the tank at 3000-5000Pa (with special emphasis on preventing zero or negative pressure in the storage tank).
Open the N2 steel cylinder valve, reduce the pressure through the pressure reducing valve, and enter the replacement pipeline. Install an exhaust port in front of valve A at the tank mouth to remove the air inside the pipeline. After sampling analysis, it is considered qualified when the oxygen content is less than 1%, and the exhaust valve is closed.
